About large touch screen

Types of large touch screens

A large touch screen is an electronic device with a wide display designed to respond to human touch. Here, ""large"" means having a screen size of at least 20 inches, while touch sensitivity can be of various types, including resistive and capacitive. Users can interact with the interface by tapping, pinching, swiping, and rotating. Large touch screens are available in different variants depending on application and usage. Evidence of this can be seen in the growing number of large touch screen manufacturers and suppliers worldwide. In 2022, the global large touch screen market was estimated to be worth $14 million. Touch screen displays are used in public areas where information needs to be provided quickly and conveniently, such as transportation, hospitality, stadiums, healthcare, education, and retail.

  • LCD touch screens: These LCD screens require a touch-sensitive overlay that can be resistive or capacitive. A capacitive overlay requires the use of an electrically responsive material. However, only conductors such as the human finger can activate the overlay. Resistive overlays, on the other hand, are touched by physically pressing the screen with any pointed object. Overlays can be built as part of the screen from the very beginning or into the resistive touchscreen. Large LCD touch screens are better for dark rooms or where the image needs to be viewed from a near-vertical angle.
  • LED touch screens: An LED screen, also known as a light-emitting diode, utilizes numerous small diodes to function as pixels in the display panel. In recent years, these screens have grown in popularity and usage. They have better image quality, longer lifespans, and lower power consumption than LCD screens. Large touch screen panels use LED technology to provide sharper images with higher resolutions.
  • Plasma touch screens: Plasma technology uses a sealed panel of inert gases that are electrically charged. Like LED and LCD screens, the plasma touch display relies on the activation of the screen to show images with high resolution and clarity. While touch sensitivity can be resistive or capacitive, the plasma screen is primarily used for better picture quality.
